Abstract (en)
[origin: EP3018961A1] The present disclosure provides a scheduling method, a coordinated-transmission node and a CCN for downlink coordinated-transmission. The scheduling method at a coordinated-transmission node side includes: receiving, by a coordinated-transmission node, scheduling privilege information corresponding to a downlink time-frequency resource from a CCN, the scheduling privilege information corresponding to the downlink time-frequency resource indicating a scheduling privilege of the coordinated-transmission node over the downlink time-frequency resource; and performing, by the coordinated-transmission node, the scheduling in accordance with the received scheduling privilege information and the latest CSI reported by the terminal. According to the embodiments of the present disclosure, the CCN merely determines the scheduling privilege of each coordinated-transmission node over the downlink time-frequency resource, and each coordinated-transmission node performs the scheduling in accordance with its scheduling privilege and the latest CSI reported by the terminal that is connected to the coordinated-transmission node. As a result, it is able to prevent the CSI from being out-of-date due to the non-ideal Backhaul transmission delay, thereby to prevent the CoMP transmission performance from being adversely affected.
